The SuperSonics said in court Friday that the city of Seattle tried to make it too expensive for them to leave town. The accusations stemmed from a previously sealed document that was admitted Friday as an exhibit in the city's lawsuit against the team.

A deal is a deal, and the SuperSonics should stay. That was the message from city of Seattle lawyers as a federal trial began Monday to determine whether the NBA franchise will be forced to stay at KeyArena until its lease expires in 2010.

Former Seattle SuperSonics owner Howard Schultz has filed a lawsuit to undo his sale of the team to an Oklahoma City-based group led by Clay Bennett, saying Bennett lied to him by promising to keep the NBA franchise in Seattle.

In filings in federal court in Seattle, Clay Bennett's ownership group for the Seattle SuperSonics says the city has participated in "significant duplicity" by not revealing the full price of projected renovations for KeyArena.

Former Seattle SuperSonics owner Howard Schultz plans to sue to get the team back from its Oklahoma City-based ownership group. The lawyer for Howard Schultz, Richard Yarmuth, said Monday he plans to sue Clay Bennett's Professional Basketball Club in the next two weeks to prevent him from moving the NBA franchise to Oklahoma City.
